Bonds/Stock Valuation Formulas

Hi:

Does anybody know of a resource that has all of these formulas, or problem/solution examples, etc...?

- Required Rate of Return
- Price of a Bond
- Yield to Maturity
- What is the Cost of Capital...

I'm getting frustrated because when I find an online resource (Google search after Google search), it's just over my head and doesn't quite relate to the problems I'm trying to work. For example, I've found the formulas for Cost of Capital of a Common Stock but it doesn't say anything about compounding and the effects it'll have on this percentage, etc...
